lacs; Serial To all whom it may concern: v v Be it known that I, CLAESA. Svnnsson, a citizen of the United States of America, re

siding at Bulialo, in the county of Erie State of New York, haveinvented a new and useful improvement in Wire Guides and Cutters, ofwhich the following is a specification.

This invention relates to a device designed inoreespecially for guidinga continuous piece of wire from a suitable feed device to a mold inwhich a soft metal seal is cast upon the end of the wire, and forcutting the wire into proper lengths. The invention, however, is notlimited to that particular, use.

A seal-casting iriachine to which the invention is applicable is shownand described "in another application "for patent filed me October '2,1901, Serial No. ,79,02t, of which the present application, is adivision. I

The principal object of this invention is the provision of a simple andreliable guiding device which will positively directand present theadvancing end of the wire to a mold or other desired device or-destination.

A further-object is to so construct and arrange the wire-guide that itserves 'at the same time as a cutter for severing the wire into suitablelengths.

Similar l rs of reference indicate core po ding parts throughout .theseveral wiews.

A is a suitable bed or table upon which the i'nachine' issupported. ,Theframe of the machine shown in. the drawings consists of an uprightlongitudinal beam A stiffened by ribs or flanges and-arranged centrallyof the machine. Located centrally on this frame is a sealca sting moldB, and above "it is a delivery nozzle 0 for the'rnolten metal which isconnected with a suitable melting pot O. The special construction of thelastnarned parts forms no part of the present invention.

.Dfindica'tes a feed device for delivering a continuous length of wireto the mold, so

as to cast one end of-the wire in the seal.

This feed-device preferably consists of a pair of horizontalfeed-rollers arranged at the front end of the machine and located at theproper distance apart to receive the wire between their peripheries andfeed the same forward. These rollers may have plain or smooth faces, butwhen the wire is to lie crimped or corrugated as in some kinds of seals,th e peripheries of the rollers are provided with vertical teeth orcorrugations, as shown in the drawings. erably taken from a continuouscoil wound upon a reel, not. shown in the drawings, and

isdirected between the feed-rollers by a Sta-- -tionary horizontalguide-tube E arranged in line with the meeting sides of the rollers.-

This guide is supported in a standard 6 rising from a bracket 6 securedto the stationary frame, as shown in Figs. 1 and 4.

- On the rear side ofjthe .feed-rollersis located a second stationarywire guide F consisting preferably of a block having a The wire isprefstraight vertical rear face and a guide-eye or channel 7" for thewire arranged in its top in line with the guide-tube E. The upper sideof this guide eye is preferably formed by a movable plate f Fig. 7,which is.capable of sliding vertically upon a stud f secured to theblock F to permit the wire to be removed in case it should bind in' theguide-eye by becoming bent or kinked. The

covering;plate f is held down in place by a .set screw 7, or othermeans, and 111 its depressed position interlocks with a stud or boredlines'in Fig. 1.

end of the plate, as shown in Fi .9, thereby preventing turning of theplate on the stud f Between the guide-block F and the sealcasting moldor other part designed to receive the wlre, is arranged a wire guide andcutter G which is adapted to directthe wire mold and the rear wire-guideF with its front side ilfl'inem ith said rear wireguide. The barrel isPIQVIdEd fiIT its eyhndrical surface with an, J-IIHUlQY'SQIIQS ofgreogs"g which extend throughout its length and are arranged to registersuccessively with said guide F so as to receive the front end of-thewire as it is fed forward by the feed rollers.

The front ends of these grooves may be flared to facilitate the entranceofthe wire into the same, as shown in Fig. 2. The straight front endofthe rotary barrel bears against the straight rear sideof theguideblock F and forms abutting edge which severs the wire at thatpoint, after the advancing end of the wire has been fed into the mold.As shown in Fig. 4, the barrel turns in a'stationary supporting sleeveof bearing II which extends nearly throughout its length and is carriedby brackets or standards I. I rising'from the frameA. An intermittent.rotary motion is imparted to the barrelfrom a rock-shaft J by anactuating pawl 7' carried by an,arm j secured to The ribs left betweenthe longitudinal grooves of the barrel form teeth with which'the pawl19' engages, as shownin Figs. 2 and 11. This pawl is held in engagementwith the barrel by a spring 7' The shaft-J which is located on the rearside of the barre]. is rocked by a pair of tappets k connected witharotary crank-disk K by rigid arms 751 and arranged to trip alternatelyover opposite sides ofan actuating arm k of the said shaft, as shown inFigs. 1, 3 and 10. This crank-disk is secured to the lower end of anupright shaft L,which is driven by bevel gears Z, Z from the horizontalmain shaft M of the machine. Retrograde movement of the barrel G isprevented by a detent pawl 12 attached to the rear end of the bearing Hand engaging with the ribs of'the barrel, as shown in Figs. 4 and 5.

The bearing H isprovlded at its front side with a longitudinaldischarge-passage or aperture 0 for the severed wires, which passageextends from end to end of the hearing, as shown in Figs. 1 and 4:. Inorder to insure the dischargeof the wires from the grooves of thebarrelupon arriving opposite the passage 0, the barrel is provided at suitableintervals with circumferential into which extend strippers or Thesestrippers bear against the bottom of said annular grooves and theirinner ends are beveled, as shown in Fig. 6,

groove-s 2) so that the wires are deflected or wedged out of the groovesupon encountering the inclined ends of the strippers and dischargedthrough the passage 0. One of these strippersis also preferably locatedat the rear end of the barrel outside. of its bearing, as shown at p inFigs. 4:, 5 and 8.

By employing a series of strippers arranged in alinement at the fronside of the barrel G, as shown. the severed lengths of wire aredischarged laterally in a straight and even manner. preventing bendingof the same and permitting the seals with the attached wires to beclosely and neatly packed.

The strippers also serve,to prevent endwise displacement of. the barrelin its bearing.

\Vhen the cutting edge of thebarrel becomes dull. the same is readilysharpened by grinding off its front end. As this opera- .tion shortensthe barrel, its bearing H is made endwise adjustable in any suitablemanner, so that it can be shifted toward'the guide-block F to compensatefor the stock removed b grinding its end. In the construction s iown inthe drawings, Figs. 5 and 6, the rear portion of said bearing isadjustably supported in the bifurcated upper end of the rear standard Iby set screws (1- arranged in the jaws of the standard, while the frontstandard I of the bearing is carried by the free end of an arm orbracket q secured to the stationary'frame. The bearing H provided with arearwardly ex tending stein (f which is clamped-in the bifurcated upperend of the standard I by a bolt Q3 so'tthat upon loosening this bolt thestem and the bearing carried by the same can be adjustedbackward orforward as required.

- The feed-rollers D are rotated intermittently, and when the inventionis embodied in a seal-casting or similar machine, their motion is sotimed that they feed the wire forward into the mold during the intervalthat the latter is open, and remain at rest while the seal is being castAny suitable driving mechanism may be employed for effecting thismovement of the feed-rollers.

The mechanism shown inthe drawings is constructed as follows: As shownin Fig. 3, the -feed-rollers are geared together by intermeshing spurgears 1', 1' of uniform diameter secured to their shafts, respectively,

and one of these shafts carries a gear pinion 'r which meshes with alarge gear wheel R'nionnted loosely on a vertical shaft or arbor r. Thislarge gear wheel is rotated intermittently for a quarter turn at a time,by an oscillating lever S one arm of which carries a spring bolt orcatch 8 of suitable construction arranged, to interlock succeswhichcause said wheel to turn forward with i the grooved barrel G with itscooperating parts performs the three-fold function of a the lever, butallow the catch to leave the notches and ride idly over the wheel duringthe, return stroke of the lever. This lever oscillates upon the shaft 1and is actuated from the crank-disk Kby a. connecting rod t, as seen inFigs. 1 and 3. The throw of this disk corresponds to the distancebetween adjacent notches of the gear wheel R.

The operation of the-machine is as follows: The feed rollers D and theguide and cutter-barrel G are rotated intermittently by the mechanismhereinbefore described, but are timed to operate alternately. end of thecontinuous wire being inserted in the front guide tube E, the same isfed forward. through the rear guide block 1* and into that guide groove9 of the barrel which for the time being registers with said rear block.This groove directs the advancing end of the wire into the mold B, whichlatter then receives a charge of molten metal, thus casting a seal uponthe end of the wire, as more fully described in the application forpatent hereinbefore referred to. After the seal has been cast,the'barrel G turns the distance from one of its guide grooves to thenext, thereby cutting off the wire at the rear edge of theguide block I?and bringing the next groove of the barrel into register with theguide-eye of said block. The movements of the wire feeder and the barrelare so timed that they both remain at rest while the seal is being castand so that the barrel turned to sever the wire immediately after thecasting operation. During the rotation of the barrel,'thc severed wireencounters the beveled ends of the strippers p 72 and i the wire withthe attached seal is discharged through the side aperture or passage 0of the bearing II.

From the foregoing it will be seen that positive guide for thewire'between the feed rollers and the mold or other element, a

wire-cutter, and a discharge device for the severed wires.

Vhile I have herein shown and described the improvement as applied to aseal-making machine, the same is not confined to that particular use,but is applicable to or useful in connection with various other machinesfor producing articles partly or wholly of wire.

I claim as my invention:
